The complete name of this program, Okoker RM to AVI DIVX WMV MPEG VCD DVD Converter&Burner, is enough to tell you what it does.
Okoker RM to AVI DVD Converter&Burner is a tool that lets you convert the popular files from Real Media (RM and RMVB) directly to these other video formats: AVI, DIVX, XVID, MPEG, VCD or SVCD. It also has its own recorder to pass them to a CD or DVD.
The Okoker RM to AVI DVD Converter&Burner user can adjust the size of the resulting video (or videos if it is a batch). It works with both PAL and NTSC systems. As is usual in this type of application, you can program the automatic shutdown of the PC when the conversion has finished.
